If that's not big enough there are also nominally 57mm TBs, 60mm and 70mm G-Ones, etc, and that's just from Schwalbe. Vee's small block tyres (V8, V12, etc) roll pretty well too, and I'm sure there are others, though not with the Road+ label.

Yeah, it seems to vary but most run a bit small. I measured the TBs soon after they came out on new Giants a couple of years back, with plastic calipers so let's say +/- a fraction of a millimetre.
The 57mm Nobby Nics were 55mm according to bicyclerollingresistance.com IIRC, so pretty close, and someone here posted that the 70mm G-One was ~74mm; another poster said 60mm G-Ones were ~56mm. Mostly Schwalbe run a bit narrow, i.e., my 28mm road tyres are about 26mm on i15 rims, 50mm Marathons are often closer to 45mm (sometimes 43mm), etc. It also depends on whether you measure across the casing or knobs (if there are any), etc.

It seems possible to make a "toothy" tire tread that performs reasonably well on road and looser stuff (I'm thinking of tires like the Compass Steilacoom, Bruce Gordon's RnR and Soma Cazadero). It would be nice to get a tire like that, but have it be about 50mm in diameter - does anyone make a tire like this?

Every competitive tire company makes a whole lineup of those!Any modern XC Racing tire has about 25 years in additional product development over those boutique panaracer options, and will handily beat them on the road too.
This is going to be messy, as actual width seems to vary slightly with rim width (someone said +2mm rim => +1mm tire), with tubes (narrower) or tubeless (+ about 3mm, give or take), casing (i.e., Compass EL = more stretch), and how on earth the manufacturer arrived at the nominal width; some tires (and companies) have been more consistently undersize than others in the past.
Then there's casing width versus maximum knob width, and at what radii/diameters these occur, which can vary quite a bit. Surly have a helpful chart of this stuff for their tires but appear to be the only ones who do; they also list OD, which doesn't vary with different rim widths.
If one is trying to ascertain whether a tire will fit a given frame or fork, then all the dimensions will be useful: outside radius/diameter, maximum casing width and knob shoulder widths (and radii for these) on various rims, height of the tire above the rim edge, etc.
Otherwise we're back to trial and error, test fitting, etc.
By the way, what minimum lateral clearance do people here is acceptable between the tire edge and inside of the fork blade, assuming no mud?

Are the 48mm Gravelking's available now? If not, have you heard when? Seems like Panaracer announced these a year ago, but I haven't seen anything yet.
Thanks!
Not quite yet. I'm not sure I'll ever get another 700c bike though. There are a lot of 50-ish mm mixed terrain tyres out or on the way at the moment, what with WTB, Soma, Clement, Schwalbe, etc.
I think we can expect to see more bikes and tyres - and hopefully some wider forks - later in the year. B+ and drops oughta be the "next big thing."

Sorry, I was making a bit of a pun with the "next big thing" comment...
A few people, like Mike Schiller here, have been experimenting with 70+ mm tyres and drop bars. With an IGH or 1x drivetrain this is easy enough to do, and with tyres like Schwalbe's G-One shouldn't be slow on the road either.
With 2x it's likely a rather wide crankset might be required, not so great from my point of view; if one sticks with ~50mm tyres the wheels don't really need to get wide or heavy, and a normal road drivetrain should clear okay. There are some reasonably light rims out there compatible with up to 2.6-3.0" tyres, so things still don't need to be super heavy.
Of course, something similar could be done with 29+ but then everything gets heavier, fit for smaller riders is more difficult, and there are fewer tyres and rims. Getting low enough gears also gets harder.
I have a frame which will accept 2.8"/70mm tyres and ~150mm Q Ritchey cranks. This has a Rohloff drivetrain and there's a drop bar shifter to suit, so that combination will likely be tried later in the year.

So does this pretty much mean that 650b drop bar bikes are mainstream now?...
All this shows is that salespersons are clueless - some things never change! And things are often similar if you ask roadies about MTBs, or either about BMX, or anything else outside their area of interest. My experience has been that most salesmen (and I say "men" here deliberately) will bluff and make stuff up rather than admit they know zip. I'm always more impressed if they admit they don't know something and offer to investigate, but maybe I'm weird...

I hadn't heard the term Male Answer Syndrome before, but have definitely been on the receiving end of it.
I think it can be both interesting and useful to ask people about stuff, and then to ask if they have personal experience of whatever it is. The best responses are to admit up front if they have used it or not, next best is to admit they're going on hearsay, least helpful is to carry on making up BS. In my experience it is useful to calibrate shop staff (and music/film/book reviewers), and can save time later on.
If they're embarassed when they catch themselves out there's hope. :-)
All right, I'll bite: what is a good measure of the mainstream?
Nustin, thanks very much for the measurements; I expect to end up with the same rims so this is very helpful indeed. Might it be possible for you to post the diameter or radius for at least one of these tyres too?
Assuming the difference in radius is similar to the difference in width then they should all fit the forks I'm considering, and BB height will vary less than I'd expected across the three (~4mm), the latter having both good and bad points.
If anyone has measurements for the 57-584 Thunder Burts that would also be appreciated.

Nice T shirt! I'm not sure I've ever heard Ryan Adams but might check him out. Looks like he has a sense of humour... :-).
Excellent, thanks Justin - I can extrapolate from there. :-)
BTW, is your front caliper now clearing the spokes okay when the bike is actually ridden?
